First letter, tire type: P= passenger car, LT=Light Truck, T= Temporary, ST= trailer.
Numbers:
255 = width
70= percentage of width that the sidewall is (how much rubber is around the rim). Low profile sport car tires will have smaller numbers (i.e. 255 20 R 17)
R 16= Means Radial Tire, wheel size 16 inches.
Radial refers to the belt organization within the tire. The other option is "D" for diagonal. R and D tires can not be used on the same vehicle.
Translation: P 255 70 R 16 is a passenger tire that is 255 mm wide, not low profile, that mounts on a 16" rim.
Adding 255 to 70 gives you a sum of 325. Adding 16 to the sum of 325 gives you a total sum of 341. To verify your answer, you can add the three numbers together on a calculator.
Yes, you can
Switching from 255/70-16 to 265/70-16 will cause your speedometer to show 58.9 mph at a true 60 mph or a difference of 1.1 mph. A better switch would be from 255/70-16 to 265/65-16. Your speedometer will be off .9 mph too slow.
That should be OK, but check carefully for any rubbing.
My 4x4 Expedition has 265/70/17......if you have 16" wheels it should be 255/70/16
That should be OK, but check carefully for any rubbing.

No, the 255/70-16 is too large and the diameter will be 1.10" too tall and your speedometer will be 2.2 mph too slow. You are going over 3% difference in size which is never advisable. You can use a 245/70 or a 245/60 but not a 255/70. Make sure all 4 tires are the same size on a 4wd vehicle.

255 = width in mm 65 is the aspect ratio 65% of 255 mm in sidewall height. R = radial tire 16 = 16 inch diameter rim so the 70 tire is 1 inch taller overall and at a speedo reading of 60 you will be going 62.1mph
Yes and 255/70 r 16 is tje biggest u can go
